Detailed Description

AVI module external interface

About the AVI module

This is external code. It provides avi file import/export and conversions. It has been adapted to make use of Blender memory management functions, and because of this it needs module blenlib. You need to provide this lib when linking with libavi.a .

Known issues with AVI

This header has not been split, since it interleaves type defines and functions. You would need the types to be able to include the function headers anyway. And, after all, it is someone else's code. So we keep it like this.
